Sun's Path and Altitude Concepts

The video tutorial by Mr. Rabbit explains the sun's path lab, focusing on calculating the altitude of the noon sun at different Earth locations. It covers equinoxes, solstices, and the sun's vertical ray, providing a step-by-step guide to plotting the sun's path and understanding seasonal changes. The tutorial also includes instructions for labeling Polaris and offers additional resources for further study.

What is the main focus of the Sun's Path Lab?

• Measuring the distance to the Sun

• Studying the phases of the Moon

• Calculating the altitude of the noon Sun

• Calculating the Earth's rotation speed

Where is the Sun's vertical ray located during an equinox?

• At the Tropic of Cancer

• At the Tropic of Capricorn

• At the equator

• At the Arctic Circle

On June 21st, where is the Sun's vertical ray located?

• At the North Pole

• At 23.5 degrees south

• At 23.5 degrees north

• At the equator

How do you calculate the noon Sun's altitude for the equinoxes?

• Add 23.5 degrees to the latitude

• Subtract the latitude from 90 degrees

• Multiply the latitude by 2

• Divide the latitude by 2

What happens to the noon Sun's altitude during the winter solstice at 66.5 degrees north?

• It decreases to zero degrees

• It remains the same

• It increases by 23.5 degrees

• It becomes negative

What is the angle of the noon Sun during the summer solstice at 66.5 degrees north?

• 90 degrees

• 66.5 degrees

• 47 degrees

• 23.5 degrees

What is the position of Polaris relative to the observer's latitude?

• It is at the North Pole

• It is at the equator

• It equals the observer's latitude

• It is always at 90 degrees

What is the duration of daylight during the summer solstice at the Arctic Circle?

• 0 hours

• 24 hours

• 6 hours

• 12 hours

What should you do if you are confused about the Sun's path models?

• Use a different textbook

• Ignore the models

• Consult the Prentice Hall review book

• Ask a friend

What is the zenith in relation to the observer?

• It is directly above the observer at 90 degrees

• It is at the horizon

• It is 45 degrees above the observer

• It is at the North Pole
